Specification of Letters Patent.

Patented July 12, 1910.

Application filed February 11, 1909. Serial No. 477,367.

To all whom it may concern:

Be it known that I, JOSEPH J. STOCKER, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Blowers, of which the following is a specification.

My invention relates to improvements in blowers and has for its object to provide a blower in which air compression is effected within a portion of the distance through which the fan blades move; the movement of the fan blades throughout the remainder of the path of their travel being through an unconfined atmosphere.

In the drawingsFigure 1 is a side elevation of a device embodying my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a transverse vertical view in mid section of the same. Fig. 4 is a sectional view of the same, taken along the line 4-4 of Fig. 3. Fig. 5 is an enlarged transverse vertical view in section of the air compression chamber 8, taken along the line 55 of Fig. 3. Fig. 6 is a similar View of the upper portion of the blower, taken along the line 6-6 of Fig. 3. Fig. 7 is an enlarged erspective fragmental View of one of the an blades 9.

As shown in the drawings, I employ a base section 10 within which is formed an air compression chamber 8 having an outlet 11; the air compression chamber 8 being sub-divided throughout its lower portion by means of the transverse partition 12. An annular housing 13 is seated upon the base section 10 in the manner illustrated in section in Fig. 3.

Upon the tubular support 14 a spider 15 is mounted carrying a shield 16. Upon the tubular support 1 1 revolving collars 17 are mounted, the collars 17 being provided with the bushing 18, and being driven by means of the pulleys 19. The collars 17 carry the wheels 20, the wheels 20 terminate in circular plates 21 between which the vanes or fan blades 9 are mounted, being secured to the plates 21 b angle members 22, as illustrated in Fig.

The blades 9 are preferably formed, as illustrated in Figs. 3 and 7, of a front metallic member 23 having two faces 24 and 25; the face 2% being approximately radially disposed, and the face 25 being at an angle to the face 24 and inclining rearwardly therefrom with reference to the path of travel of the blade 9. The rear portion of each of the blades 9 is formed of the curved metallic member 26; a wood filler being interposed between the metallic members 23 and 26, which members are secured together and through said wood filling 27 by means of bolts 28.

The blower thus described, therefore, has an air compression chamber contained within a base section, upon which base section the housing 13 is mounted, the inner surface of its peripheral portion being in the arc of a circle; a shield 16 being mounted within the housing 13 and concentric there with, the extremities of the shield 16 being terminated substantially in radial alinement with the extremities of the housing 13, the housing 13 and shield 16, thus mounted, forming a passage in the form of a portion of a ring communicating at each end with the compression chamber. The fan blades 9 are so mounted and propelled as to travel through the passage thus formed and through the upper part of the compression chamber 8, their effective work being accomplished through that segmental portion of their path which is within the air compression chamber 8.

The mode of operation of the blower thus described is as follows: The housing 13 be ing open at its sides, the blades 9 travel through a practically unconfined atmosphere from the point indicated in Fig. 3 by the numeral 29 to the point indicated in the same figure by the numeral 30. The base member 10 is projected inwardly with reference to the tubular support 1 1 between the points 29 and 30 to form the side walls 31; each of the blades 9 upon reaching the point 30 in its revolution begins its function of compressing air into the air compression chamber 8, and the uniform outflow of the air so compressed is effected by the division of the air compression chamber 8 into two sections by means of the transverse partition 12; the compressed air finding its exit through the outlet 11. Thus, the work of each blade in the compression of air is of fected between the points 30 and 29 and within the air compression chamber 8; while throughout the remainder of its path of travel the blade is not met by the resistance of air under pressure and the consequent retardation of the wheel 20 to which it is attached.

The tubular support 14 is cooled during the operation of the blower by being kept supplied with oil through the oil cups 31; the tubular support 1 1 being closed at its ends by means of the plugs 32.

While in the foregoing description I have described the housing 13 as a part of the blower of my invention, the housing 13 may be omitted, if desired, without destroying the efliciency of the device, or departing from my invention. The curved shield 16 will serve to prevent the upward suction and distribution of air by the vanes or fan blades 9 whether or not the housing 13 is employed; although the best results are obtained by the employment of the housing 13 as heretofore described.

Having fully described my invention, what I claim as new and desire to have secured to me by the grant of Letters Patent, is:

1. In a blower, the combination with a wheel and vanes carried thereby of a casing in which said wheel is mounted to rotate and which contains a chamber and a passage in the form of a portion of a ring, the ends of which are in communication with said chamher, said chamber and passage being in such position that the vanes traverse them as they rotate, the chamber being provided with an outlet opening outside the path of the vanes and with an inlet opening within the path of the vanes and the passage being cut ofl from free communication with both the inlet and the outlet, substantially as described.

2. In a blower, the combination with a revolving member and vanes carried thereby, of a casing on which said revolving member is mounted, which casin contains an air compression chamber and a passage in the form of a portion of a ring, the ends of which passage are in communication with said chamber, said chamber and passage be ing so positioned that the vanes traverse them as they rotate, the air compression chamber being provided with an outlet opening outside of the path of the vanes and with an inlet opening within the path of the vanes, and the passage terminating at the ends of said inlet, substantially as described.

3. In a blower, the combination with a base section containing an air compression chamber, of a housing mounted on said base section, the inner surface of the peripheral portion of which is in the arc of a circle; a shield mounted within the housing, the exterior of the peripheral portion of which is in the arc of a circle concentric with the housing, said base section, housing and shield forming a circular path, the portion of which path that is within the air compres sion chamber having an inlet formed between the extremities of the shield; a plurality of vanes adapted to travel through said path; two parallel wheels mounted concentrically wit-h reference to said path and whereby said vanes are carried, and means for rotating said wheels, substantially as described.

1. In a blower, the combination with a base section containing an air compression chamber, of a revolving member and vanes carried thereby and a shield mounted concentrically with said revolving member and within the path of travel of the vanes, said revolving member and shield being so positioned that the vanes travel around the periphery of the shield as they rotate, and the ends of the shield terminating at points above the air compression chamber, the air compression chamber being provided with an outlet opening and an inlet opening, between which outlet opening and inlet opening said vanes travel between the ends of said shield, substantially as described.

In a blower, the combination with a base section containing an air compression chamber, a shield mounted above the base section, the exterior of the peripheral portion of which shield is in the arc of a circle, a plurality of vanes adapted to travel around the periphery of said shield and through the air compression chamber, the portion of the path of travel of said vanes which is within the air compression chamher having an inlet formed between the extremities of the shield and the air compression chamber having an outlet; and means for revolving said vanes, substantially as described.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
